DataStax Academy FAQ

DataStax Academy migrated to a new learning management system (LMS) in July 2020. We are also moving to a new Cassandra Certification process so there are changes to exam bookings, voucher system and issuing of certificates.

Issue with step 7 in exercise 1 of the DS201 Academy course

ubuntu@ds201-node1:~/node/bin$ ./dsetool status
Warning: Not able to read Analytics Master data, SparkMaster data may not be correct.
DC: Cassandra       Workload: Cassandra      Graph: no
======================================================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address   Load       Owns Token Rack  Health [0,1]
UN 127.0.0.1 130.99 KiB ?    0     rack1 0.70

Then, When I do the exercise 2:

ubuntu@ds201-node1:~/node/bin$ /home/ubuntu/node/resources/cassandra/bin/cqlsh
Connection error: ('Unable to connect to any servers', {'127.0.0.1': ReadTimeout('Error from server: code=1200 [Coordinator node timed out waiting for replica nodes\' responses] message="Operation timed out - received only 0 responses." info={\'received_responses\': 0, \'required_responses\': 1, \'consistency\': \'ONE\'}',)})

For exercise 1 status part, the other status is just like the example. But I am not sure if this warning in the first line is right: Warning: Not able to read Analytics Master data, SparkMaster data may not be correct.

For exercise 2. I get the connection error. I do not know how to fix it to start cqlsh.

I am using the virtual box. Thanks!
